Abstract

La présente invention concerne un moteur à combustion interne rotatif du type Wankel présentant un logement ayant une surface périphérique interne épitrochoïdale à deux lobes, un arbre tourillonné dans des logements d'extrémité et un rotor monté de manière excentrique sur l'arbre et commandé pour se mettre en rotation à un tiers de la vitesse dudit arbre, des chambres de travail étant formées entre les flancs du rotor et les logements dont le volume varie à mesure que le rotor tourne. Le rotor est refroidi par un système de circuit entièrement fermé dans lequel des gaz sous pression sont mis en circulation par un ventilateur centrifuge qui est monté directement sur l'arbre excentrique principal, et fait circuler les gaz à travers un échangeur de chaleur qui est intégré dans le secteur de refroidissement du logement du rotor, tous les composants étant enfermés à l'intérieur du système sous pression et seul un arbre d'entraînement utilisant un seul ensemble joint d'arbre à haute pression émerge de ce système.
